SEGIFCATION forming part of Letters Patent No.

Application tiled July 1.9, 1880.

To all 'whom it may concern:

Be it known that l', SAMUEL l\l. RXCHARD- son, of Woburn, county of "ilddlesex, State ot' lllassachnsetts, have invented an Improvement in Ordnance, ot' which the ifollowing description, in connection with the accompanying drawings, is a specification.

rlhis invention relates to ordnance, and has for ,its object improvements in mechanism for easily and quickly operating the breechpiece,the said mechanism swinging the breechpiecc laterally and returning it to its position at the rear el' the gun through the agency of eccentrics, as hereinafter described.

I have also applied to the gun an extractor operated by hooks carried by arms supporting the movable breech-piece, as hereinafter dcscribed.

Figure vided with my improvements, ing closed; Fig. 2, a rear end view, the breech-piece being turned aside, Fig. 4, a 'partial longitudinal vertical section on the line y? fvl,ll`ig. 2; Fig. 5, a detail of the cam ior directing l. is a side elevation ot' a gun prethe breech bethe movement ot' the breech-piece as it is operated by the cccentrics, and Fi g. G a detail ot the devices i'or operatin g the extractor'.

The body A ot' the gun, having trunnions n, may be boredor ritled in any usual manner, and be made ol' any usuel material.

'lhe breech-piece U, provided with the usual iiring-pin 5, is carried at the ends oi' arms o f, prete ably made in one piece with the breech, the ends of the said arms being shaped to iit eccentrics g lt mounted on projections or bea-rings tj, the arms and eccentrics being seeuret against lateral movement one over the other by means of thc eccentricstraps entering grooves in the peripheries of the eccentrics. (SeeFig. hese eccentrics are rotated to move the arms longitudinally, and consequently the breech-piece, back away from the rear end of the gun by means oi links lo lc', `1li g. l, and dottedlines, liig. il, connected with the pins le? on the said ecccntrics, and with arms 7.13 le* ot' aroclr-shaft, l, held inlngs or bearings in, the rock-shalt deriving movement from a link, a, connected with a slide, o, adapthaving one or NG RDNANOE.

more handles connected at apoint between its ends with such slide.

A locking device, r, shown as a screw and moving with the handle 1;, cooperatingl with a sector, s, holds the lever in either of its two positions.

rThe cartridge t',ot` any usual or proper make or material, has its rim seated in a cartridgeextractor, a, (see Figs and 4,) connected with arms c held in suitable gnidewa-ys in the gun, so that such arms and extractor may be moved longitudinally to eject the cartridge shell. rllhcs'e arms o are provided with pins w, which are engaged by spring-hooks w, connected at f r/ with the arms c f, such arms, when moved longitudinally backward to uncover the breech ot' the gun, drawing the arms 'u and cartridgeextractor a ou Upon cach eccentric have placed a pin or roller-stud, a', which is extended into a camshaped slot, al,in aplate,a. These cam-slots are so shaped, substantially as shown, that as the arms e j and breech-piece are moved outward along the gun by the eceentricsy the said studs, acting against the 1 breech-piece to he moved laterally awaf,1 from, and so as te completely uncover, the rear ot' l" As the arms cfcontinue the gun, as in 1.* 1g.

their movement in the direction of the arrow, Fig. l, the hooks ot' the spring-hooks release the pins w, and the cams or ribs 6L', fixed on the arms e f, meet the pins w at their upper sides and move the arms o in the opposite'direction, thus drawing the extractor u back into the breech ot' the gun to receive and hold the cartridge.

As the handle p is moved from the dotted to the full line position, Fie'. `l, to close the breech-piece, the springs ac, as the arms move longitudinally toward the nozzle of the gun, are moved laterally by reason ot' their inclined ends, which strike the pins Iw, but after passing the said pins the hooks engage with them. The sights will be all as usual.

The dotted lines at the lett ot' ldic.l 4 show the extractor moved out, as it will be when the breech-piece is in the position, Fig.

instead ot moving the slide o by means ot' the lever t, it is obvious that l might provide one edge oi the slide with proper teeth to be engaged by n worm or screw, to thus move the seid slide bythe worm or screw. This would be desirable in connection with very heavy ordnance, wherein considerable power would be required to move the eeeentrics and swing e heavy breech-piece.

I claim- 1. The breeehpiece und its arms combined with the eeeentries and mechanism to actuete the eecentries, substantially :is described, t0 move the erms :tud breeelrpiece longitudinally with relntion to the gun :it euch operation ol' the breech-piece7 substantially es described.

2. The breech-piece and its arms combined with the eceentrics to move them longitudinally, and with the stud and cenrslotted plate to cause the breech-piece to be swung laterally away from the breech ot' the gun, substantially as described.

3. The combination, with the arms e fend zo their hooks, et' the extraetornnd its arms o, to operate substnntiel'l y as described.

4. The arms of end their cams or ribs d', combined with the .firms of the extractor provided with pins f1r,to opernte substantially es. described.

5. The lever p, slide o, link o1., and roekine; sln1t`t,z1nd links k k,combinedwithsueh shaft, and 'the eceentries to operate them7 substantially es described.

'In testimony whereof l lnwesigned my name to this specifica-tion in thepresenceof twosubscribing witnesses.
